How is sleep debt calculated?

Sleep debt is calculated by finding the difference between the sleep your body needs (usually 7-9 hours) and the actual sleep you get. Our calculator uses your wake-up and bedtime to give an instant result.

Can I recover from years of sleep debt?

Yes, but it takes time. Consistent sleep schedules and 90-minute sleep cycles help your brain and body recover gradually. Using a sleep debt calculator helps track your progress.
